By referring to the drawings it will be seen that the sampling machine is used in connection with a conveyer 5 which is disposed horizontally, and which has a bottom 6 with an opening 7. The top 8 of the sampling machine has an opening 9 with which the opening 7 in the bottom 6 of the conveyer communicates. Rotatably mounted in the chamber 10 in the sampling machine there is a sampler-wheel 11, this samplerwheel 11 being secured to a shaft 12 journaled in bearings 13 secured to the side'of the sampling machine. The top 8 of the sam-. pling machine at its opening 9 converges downwardly as illustrated at 14, to the sides and periphery of the sampler-wheel 11, so that this sampler-wheel 11 will serve to close the opening 9 and prevent the material which is passing through the conveyer 5 from falling therethrough. The samplerwheel 11 is provided with a pocket 15 having an end 16 which is disposed substantially radially, and a bottom 17 which is disposed substantially at right angles to the end 16. When the sampler-wheel 11 is rotated in the direction indicated by the arrow in Fig. 1 pocket will receive material falling through the openings 7 and 9, and will deposit this material in a box 18 at the bottom of the sampling machine. Journaled in bearings 19 in the top '8 of the sampling machine, there is a shaft 20, to

which agitators 21 are secured, these agita tors 21 serving to prevent the material passing throughthe openings 7 and 9 from becoming clogged. r

At the bottom'of the box 18 there is-a drawer-22 which serves to permit the ready removal of some of the samples which have been collected and have been deposited therein. As a means of mixing the material which is collectedin thedrawer 22,1 provide agitators'23 which are secured to a shaft 24 j ournaled 'in'bearin'g's 25 secured to the sides of the'sampling machine.

In'bearings 26 atone side of the sampling machine there is journaled a shaft 27 to which a pulley 28 is secured, a gear 29 being also secured to the shaft 27 which meshes with a gear 30 secured to the shaft 12 and with a gear 31 secured to the shaft 20.

"Theredsalso secured to the shaft 12 a sprocket'wheel 32 which isconnected with a sprocketwheel 33 secured to the shaft 24 by means of a sprocket chain34; Openings 35 are made in the walls of the sampling machine at and below the sampler-wheel 11,- and glass panes 36 are secured in these openings so that the operator may at all times observe whet-her or not the samples are being taken of the material passing through the conveyer 5. The top 8 of the sampling machine has bracket arms 37 which are secured to opposite sides of the conveyer 5.

Having thus described the invention, I claim as new and desire to secure by Letters Patent:

1. In a sampling machine, a conveyer having a bottom with an opening intermediate its ends, means for advancing material longitudinally of the bottom of the conveyer, a sampler wheel rotatably mounted below the opening, means connecting the conveyer bottom .around its opening with the sampler wheel at its periphery, the sampler wheel having a pocket in its periphery for the purpose specified.

2. In a sampling machine, a conveyer having a bottom with an opening intermediate its ends, a sampler wheel rotatably mounted below the opening, means connecting the conveyer bottom around its opening with the sampler wheel at its periphery, the sampler wheel having a pocket in its periphery, a box disposed below the sampler wheel, a drawer in the box and an agitator in the box for mixing the material collected in the drawer.

3. In a sampling machine, a conveyer having a bottom with an opening intermediate its ends, a sampler wheel rotatably mounted below the opening, means connect ing the conveyor bottom around its opening with the sampler wheel at its periphery, the sampler wheel having a pocket in its periphery, a box disposed below the sampler wheel, a drawer in the box, an agitator in the box for mixing the material collected in the drawer, an agitator in the opening in thebottom of the conveyor, and means for operating the sampler wheel and the two agitators synchronously.

4. In a sampling machine, a member having an opening, a sampler wheel rotatably mounted with its periphery engaging the member at the opening to close the latter, the sampler wheel having a pocket in its periphery, one end of which is disposed substantially radially relative to the axis of the sampler wheel, the bottom of the pocket being disposed substantially at right angles to the said end and extending to the periphery of the sampler wheel.

5. In a sampling machine, a member having an opening, a sampler wheel rotatably mounted with its periphery engaging the member at the opening to close the latter, the sampler wheel having a pocket in its periphery one end of which is disposed substantially radially relatively to the axis of the wheel, the bottom of the pocket being disposed substantially at right angles to the said end and extending to the periphery of the sampler wheel, and means to rotate the sampler wheel in a direction where the bottom of the pocket at the periphery of the sampler wheel. will first pass the opening in the member.

6. In a sampling machine, a member having an opening, a sampler wheel rotatably mounted with its periphery engaging the member at the opening to close the latter, the sampler wheel having a pocket in its periphery, an agitator in the opening in the member, and means to operate the agitator and the sampler wheel.

7 In a sampling machine, a conveyer having a bottom with an opening interme diate its ends, a sampler wheel rotatably mounted below the opening, means connecting the conveyer bottom at its opening with the sampler wheel at its periphery to close the opening, the sampler wheel having a pocket in its periphery, a box disposed below the sampler wheel, a drawer in the box, an agitator in the box for mixing the material collected in the drawer, and means to operate the agitator and the's'ampler wheel.
